Hi PG Student,
If you are just starting communication with your controller via RS-232, I would first test out serial port communication simply by doing a
Serial Loopback Test.
Once you've verified that the port works, you can start running some simple programs in LabVIEW to read/write using the serial port. Serial example programs can be found under
Help->Find Examples.... Select the
Browse tab, then
Hardware Input and Output->Serial. Try the LabVIEW<->Serial.vi first. Take a look at the block diagram to see more about data can be written to and read from a serial port.
More serial support information can
be found below:
